PY 81 as power rectifiers?

[pwdrive]

Any pitfalls to watch for if the audio transformer is mounted away from the chassis completely? it would mean quite long primary connection wires to the anode (10 or 15 cm). Hum is hardly noticeable where it is, but it is noticeable.

Not in an electrical sense, I had approx. 2 metres of twin cable to connect HT and OP anode to an output transformer in some of the loudspeaker cabinets I had, eg: HRO receiver to loudspeaker, never had any problems.....The standard HRO receiver never had an output transformer fitted on/in the receiver.

Picture of my old HRO receiver(s) and loudspeaker unit, the one in the background is my original HRO Senior, the one under the loudspeaker is a later version, the Reception Set R106 MKII...aka a HRO-5t, both most excellent receivers.
